Specification of Letters Patent.

Patented Feb. 20, 1917.

Application filed May 8, 1918. Serial No. 95,994.

To all whom it may concern:

Be it known that I, EMIL JoHNsoN, a citizen of the United States, anda resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Photographic- Printing Frames, of which the following is a specification.

My invention relates to improvements in photographic printing frames and has for its object theproduction of a device of this character adapted to accommodate a photographic negative either in the form of a film or a plate. v

A further object is the production of a photographic printing frame in which the negative film or plate may be shifted to any position desired in order to facilitate printing the desired portion thereof, and further a printing frame which will be ofsimple construction and efiicient in use.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a perspective view of the photographic printing frame embodying the invention,

Fig. 2 is a vertical-transverse section of the frame,

Fig. 3 is a top plan view thereof,

Fig. 4 is a side elevation thereof, and

Fig. 5 is a vertical longitudinal section of the frame.

The preferred form of construction as illustrated in the drawings comprises a rectangular frame member 1 having a rectangular exposure opening over which arranged a transparent plate 2. The plate 2 is countersunk in the inner side of frame member 1 and rigidly fastened therein, so that the upper side of said plate will be flush with the corresponding side of said frame member as clearly shown in Figs. 2 and 5.

Arranged upon the upper side of frame member 1 is a second frame member 3 of substantially the same form as frame member 1, said frame members being hingedly connected at one side'by'means of hinges 4. Ea'chof said hinges consists of two leaves 4: and 4", the leaf 4 being rigidly secured to the frame member 1, the leaf 4 being comparatively long and resilient and secured at its extreme outer end to the frame member 3 as clearly shown in Figs. 3 and 4. With this arrangement it will be seen that a yielding connection is established by the hinges 4 between the corresponding ends of frame members 1 and 3 so as to permit of either a negative film or plate being inserted between said frame members.

The opposite ends of frame members 1 and 3 are also yieldingly connected for the same reason, this connection being formed by a substantially U-shaped spring clip 5 which is hingedly secured as at 6 to the frame member 1. The outer or free end of said spring clip is adapted to engage over thecorresponding-end of frame member 3 as clearly shown in the several views. In order to prevent accidental disengagement of the clip 5 of the frame member 3 the hinged or pivoted end of said spring is inset in the frame member 1, as clearly shown in Fig. 5, so that the hinge or axis of said clip will be substantially directly opposite the point of engagement ofthe free end thereof with the frame member 3.

The frame member 3 is formed with a rectangular opening corresponding with the exposure opening in the framc 1, and arranged in this opening-is a clamping member or plate hingedly secured at one end to the frame member 3 by hinges 8. A re silient fastening arm 9 is pivotally fastened to the free end of member 7 the outer end of said arm being adapted for engagement under an angular stop 10 provided upon the corresponding end of frame member 3 in order to yieldingly hold the other end of said clamping plate in operative position. The under side of clamping plate 7 is provided with a resilient covering 11 of felt or other suitable material.

In using the printing frame the negative mm or plate is first inserted between the frame members 1 and 3, the latter being ieldingly pressed into engagement with the film orplate by the resilient leaves 4" of the hinges 4 and the spring clip 5. The sensitive photographic paper is then arranged over the negative, being held in position byfthe clamping .plate 7. Where a number of prints are to be made from one negative, it is only necessary to release the clamping plate 7 in the insertion and re- Fun Cir

moval of the successive pieces of sensitive paper, the negative being held fast between the frame members 1 and 2.

The joint between the frame members 1 and 2 being open and unobstructed, it is evident that the negative may be shifted in the frame to a position in which perhaps one side or corner of the same projects from the frame, thus facilitating the arrangement of the negative in order to secure a print of a desired portion of the same as will. be readily understood. Were the joint between the frame members obstructed it is of course apparent that the shifting of the negative to the position mentioned would not be permitted.

While 1 have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. 1, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

l. A. photographic printing device comprising a frame member having an exposure opening; a transparent plate arranged over said opening; a second frame member hingedly connected with said first mentioned frame member and having an opening corresponding with said exposure opening; and a clamping member hingedly secured to said first mentioned frame member and positioned in the opening therein, substantially as described.

A photographic printing device comprising a frame member having an exposure o 'iening; a transparent plate arranged over said opening; a second frame member arranged over said first mentioned frame member having an opening corresponding with said exposure opening; a yielding hinge connection between said frame members; and a clamping member arranged. in said opening in said second mentioned frame member, substantially as described.
